What is a HEX Color Code?

A HEX color code is a way of specifying color using hexadecimal values. In web design and CSS, hex codes are the most common and widely supported color format.

Hex color codes always start with a hash symbol (#) followed by six characters (0-9, A-F). These six characters represent the intensity of red, green, and blue in the color.

HEX Code Structure

#RRGGBB
  • RR: Red component (00-FF)
  • GG: Green component (00-FF)
  • BB: Blue component (00-FF)

Each pair of characters represents a value from 0 (00) to 255 (FF) in hexadecimal notation.

HEX Color Examples

Pure Red

#FF0000

FF = Maximum Red (255)

00 = No Green (0)

00 = No Blue (0)

Sky Blue

#4A90E2

4A = Medium Red (74)

90 = High Green (144)

E2 = Very High Blue (226)

Medium Gray

#8C8C8C

When all three values are the same, you get a shade of gray.

Using HEX Colors in Web Development

HEX Colors in CSS

.header {
  background-color: #4A90E2;
  color: #FFFFFF;
}

.button {
  background-color: #FF5733;
  border: 2px solid #E74C3C;
}

p {
  color: #333333; /* Dark gray */
}

HEX codes are the most common color format in CSS due to their compactness and universal support across all browsers.

HEX Colors in HTML

<!-- Using hex codes for inline styling -->
<div style="color: #4A90E2;">
  This text is sky blue
</div>

<p style="background-color: #F5F5F5; 
          color: #333333;">
  Gray text on light gray background
</p>

<span style="border: 3px solid #FF3B30;">
  Red border
</span>

While it's generally better to use CSS for styling, HEX codes can also be used directly in HTML inline styles.

HEX Color Tips & Tricks

  • •

    3-digit shorthand: If each channel has repeated digits (e.g., #FFAA33), you can use shorthand notation (#FA3).

  • •

    Modern alpha support: Modern browsers support 8-digit hex with alpha values (e.g., #FF000080 for semi-transparent red).

  • •

    Color variables: In modern CSS, store hex codes as variables: :root { --primary: #4A90E2; }

  • •

    Consistency matters: Maintain a consistent color palette throughout your site for better UX and brand identity.

HEX to RGB/HSL Converter

Try our simple converter to transform HEX color codes into RGB and HSL values:

Converted Values:

RGB Value:

rgb(74, 144, 226)

HSL Value:

hsl(210, 73%, 59%)

You can use these values interchangeably in CSS. RGB and HSL formats also support alpha transparency: rgba() and hsla().

Frequently Asked Questions About HEX Color Codes

Why are HEX codes used instead of regular numbers?

HEX codes use hexadecimal notation (base-16) instead of decimal (base-10) because it allows each byte (0-255) to be represented by exactly two characters. This creates a more compact and consistent notation where each color component (R, G, B) is always represented by two characters, making the format more readable an color component (R, G, B) is always represented by exactly two characters, making the format more readable and easier to work with in code. Additionally, hexadecimal is a natural fit for computing where values are often stored in 8-bit bytes.

Can I use HEX color codes in all browsers?

Yes, all modern browsers have excellent support for 6-digit HEX color codes. They're one of the most universally supported ways to specify colors in web development. The 3-digit shorthand is also widely supported. However, newer features like 8-digit HEX codes (with alpha transparency) might not work in some older browsers. For the broadest compatibility, stick to 6-digit HEX codes or use rgba() when you need transparency.

How do I find the HEX code for a specific color?

There are several ways to find HEX codes for colors:

  • Use our color picker tool on this website
  • Use the color picker tool in design software like Photoshop, Illustrator, or Figma
  • Use browser developer tools to inspect elements with the color you want
  • Use a browser extension like ColorZilla to pick colors from any webpage
  • Reference color charts or use color name databases for common colors

How do I choose accessible color combinations?

When choosing colors for text and backgrounds, ensure there's sufficient contrast for readability. The Web Content Accessibility Guidelines (WCAG) recommend a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. You can use contrast checker tools where you input your HEX codes to verify if your color combinations meet accessibility standards. Also consider color blindness—avoid relying solely on color to convey important information, and test your design with color blindness simulators.

Frequently Asked Questions

What is a HEX color code and how does it work?

A HEX color code is a 6-digit hexadecimal representation of color starting with #. It uses the format #RRGGBB where RR (red), GG (green), and BB (blue) are hexadecimal values from 00 to FF (0-255 in decimal). For example, #FF0000 is pure red (255 red, 0 green, 0 blue).

How do I convert HEX to RGB or other color formats?

Use our conversion tools to convert HEX to RGB, HSL, or other formats. For manual conversion: split the HEX code into pairs (e.g., #FF5733 becomes FF, 57, 33), then convert each pair from hexadecimal to decimal (255, 87, 51). Our automated tools provide instant, accurate conversions.

What are the advantages of using HEX color codes in web development?

HEX codes offer several advantages: compact 6-character format, universal browser support, easy to copy/paste and share, widely supported in design tools, consistent across platforms, and efficient for CSS styling. They're the most common color format for web development.

Can I use HEX codes for transparency and alpha values?

Traditional 6-digit HEX codes don't support transparency. However, modern CSS supports 8-digit HEX codes where the last two digits represent alpha (e.g., #FF000080 for 50% transparent red). For broader compatibility, use rgba() or hsla() functions for transparency effects.

How do I choose the right HEX colors for my website?

Choose HEX colors by considering your brand identity, target audience, and accessibility. Use our color picker tools to explore options, ensure sufficient contrast ratios (4.5:1 minimum for text), test across devices, and create cohesive color schemes using color theory principles.

What's the difference between 3-digit and 6-digit HEX codes?

3-digit HEX codes (#RGB) are shorthand where each digit is repeated (#RGB becomes #RRGGBB). For example, #F00 equals #FF0000. 3-digit codes work for 4,096 colors, while 6-digit codes provide access to over 16 million colors for precise color control.

Are HEX color codes the same across all devices and browsers?

HEX color codes are standardized and display consistently across modern browsers. However, actual color appearance may vary slightly due to device screen technology, color profiles, brightness settings, and viewing conditions. For critical color matching, test on target devices.

How do I extract HEX colors from images or existing websites?

Use our image color extraction tool to upload images and get HEX codes from specific pixels. For websites, use browser developer tools, color picker extensions like ColorZilla, or our color finder tools. Many design software packages also include color sampling tools.
